Key Points about Vestibular neuronitis
- Definition: Vestibular neuronitis is an inner ear disorder characterised by acute onset vertigo, caused by inflammation of the vestibular nerve, leading to disruption of balance but with no hearing loss or tinnitus.
- Causes:
- Viral infections affecting the vestibular nerve, often following a respiratory tract infection.
- Idiopathic inflammation of the vestibular nerve.
- Symptoms:
- Sudden onset of severe vertigo lasting several hours to days.
- Nausea and vomiting due to vertigo.
- Imbalance and difficulty walking.
- Absence of hearing loss or tinnitus, distinguishing it from other causes of vertigo.
- Investigations:
- Clinical diagnosis based on history and examination, including:
- Head impulse test: Used to assess the vestibulo-ocular reflex.
- Romberg and Unterberger tests: Assess balance and coordination.
- MRI scan: To rule out central causes of vertigo such as stroke or brain lesions in atypical or severe cases.
- Clinical diagnosis based on history and examination, including:
- Management:
- Symptomatic treatment: Antiemetics like prochlorperazine or antihistamines (e.g., cinnarizine) to control nausea and dizziness during acute attacks.
- Vestibular rehabilitation exercises: To help restore balance function in the days and weeks after the acute episode.
- Corticosteroids: May be used in some cases to reduce inflammation of the vestibular nerve.
- Complications:
- Persistent imbalance or dizziness lasting for weeks or months (chronic vestibulopathy).
- Anxiety and avoidance of movement due to fear of triggering vertigo.
- Rarely, recurrence of the condition.
